IMPROVEMENT IN CURB-MILLe c its rlgthnle :mirth tu in tlges intent @that tmb uniting @mrt uf tige ttm.

.To ALL WHOM 1T MAY' coNoitRN;

Be it known that I, JAMES .MAGADAM, of Little Falls, Herkimer county, State oNew York, have invented an Improved Curd-Mill or Cmd-Breaker; and I do hereby declare the following description and accompanying drawings are suicient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements 4Without. further invention or experiment.

I The nature of my-invention and improvement consists in providing a frame, designed to be placed upon a cheese-tub or vat, and to support a box or hopper, having in its lower part a' cylinder, with long teeth or pins, arranged spirally upon and projecting from its surface, said teeth passing, as the cylinder revolves, between horizontal bars 6r plates, placed beneath the cylinder, in a direction at right angles to itsaz'zis, said cylinder being provided with a pinion, gear, and crank, and a iiy-wheel for revolving it.

In describingr my card-mill, I refer to the accompanying drawings, forming part of this specification- Figure 1 being a. plan or top view of my mill, and

Figure 2 a vertical section of` the same, through the line :v :e on iig. 1.

A isa frame, intended to' be placed upon the tub or vat that is to receive the broken curd, and to support the box or hopper B, into which the curd to be broken is pnt. i C'is a cylinder,`-the lprojections oflits axis rest-v ing upon and turning in boxeson the* fram A, and provided withlong' teeth or pins, E E, arranged spirallyr upon and projecting from its circumference, and so as to pass, as the cylinder revolves, between the horizorital plates 4or bars D D, extending across the bottom of the hopper, just beneath the cylinder, and in a direction at v right angles to its axis, and being set vertically edgewise so as more readily to divide and comminute the curd as it passes down. The pinion F, on the axis ofthe cylinder C, is turned bythe gear-wheelr G, operated by the crank H, the fly-wheel I tending to maintain and equalize the motion.V The arms J J, extending out from the frame A, are convenient for removing the mill or carrying it from place to place, and for supporting it upon a wat or tub.

Portions of curd being placed in the hopper and the crank turned, the teeth on the revolving cylinder tear eff pieces ofthe same, carrying them down through the grate beneath, the bars of' which aid in breaking up the curd and comminuting it to the degree required.

What I claim as my invention, rand desire to secure by Letters Patent, is

The combination and arrangement of the hopper, provided with a grate of straight bars beneath, and the toothed-cylinder turning in said hopper, and having its teeth to pass down between said bars, substantially asl described, and forcthe purposes set forth.

JAMES MAGADAM.
